It is traditional in western society for children to be taken care of by parents or legal guardians. In families where children live with one or both of their parents, the childcare role may also be taken on by the extended family. In the absence of one or both parents and the extended family willing to care for the children, orphanages are a way of providing for children's care, housing, and schooling.The three main types of child care options for most American working families include in-home care, family child care, and child care centers. Many American working families are two-job households, and this means that childcare is often delegated to childminders or crèches on a full-time or part-time basis.In-home care typically is provided by nannies, au-pairs, or friends and family. The child is watched inside their or the child carer's home, reducing exposure to outside children and illnesses. Depending on the number of children in the home, the children utilizing in-home care enjoy the greatest amount of interaction with their caregiver, forming a close bond. There are no required licensing or background checks for in-home care, making parental vigilance essential in choosing an appropriate caregiver. Nanny and au-pair services provide certified caregivers and the cost of in-home care is the highest of childcare options per child, though a household with many children may find this the most convenient and affordable option.At the same time, a nanny or au-pairs are not always the best methods of childcare. It confines the child into a world of their own. It keeps them from interacting with other children a lot of the time. As mentioned the caregivers do not need licenses or background checks so there is no way of telling if a person is really qualified or has a criminal background. These things should be taken in consideration when making a choice.Family child care is provided from a care giver's personal home, making the atmosphere most similar to a child's home. State licensing requirements vary, so the parent should conduct careful interviews and home inspections, as well as complete a background check on the caregiver's license. Any complaints against the caregiver will be documented and available for public record. Family care is generally the most affordable childcare option, and offers flexibility in hours available for care. In addition, family care generally has a small ratio of children in care, allowing for more interaction between child and provider than would be had at a commercial care center.Commercial care centers are open for set hours, and provide a standardized and regulated system of care for children. Parents may choose from a commercial care center close to their work, and some companies offer care at their facilities. Active children may thrive in the educational activities provided by a quality commercial care center, but according to the National Center for Early Development and Learning, children from low quality centers may be significantly less advanced in terms of vocabulary and reading skills. Classes are usually largest in this type of care, ratios of children to adult caregivers will vary according to state licensing requirements.Pre-school is often the term used to refer to child care centers that care primarily for 3 and 4 year old children. Preschool can be based in a center, family child care home or a public school. Head Startis a federally funded program for low income children ages 3 and 4 and their families. Similarly Early Head Start serves low income children birth to 3 years of age.[2]Regardless of type of care chosen, a quality care provider should provide children with light, bright and clean areas to play as well as separate sleeping and eating areas.Most western countries also have compulsory education during which the great majority of children are at school starting from five or six years of age.
